    Windows 8


    Hopefully I'm doing this right. I attached the BSOD using the SF Diagnostic Tool here. I've been having these BSOD's randomly. I also ran WhoCrashed:

    This was probably caused by the following module: tcpip.sys (tcpip+0x93FA5)
    Bugcheck code: 0xD1 (0x3C, 0x2, 0x1, 0xFFFFF88001B2DFA5)
    file path: C:\Windows\system32\drivers\tcpip.sys
    product: Microsoft® Windows® Operating System
    company: Microsoft Corporation
    description: TCP/IP Driver
    Bug check description: This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.
    This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
    The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.

    Thanks for any help you can give!

    It seems that your Wifi driver is the cause of the problem and upon closer inspection it seems to be rather old:

    NETwNs64    fffff880`04293000    fffff880`04b19000    Thu Oct 06 10:45:03 2011 (4e8dbeef)    00839bd1        NETwNs64.sys
    you can find updates for it either on your computer manufacturer's website or on the Intel wbsite:

    Thanks for such a quick response! I ran the update utility on Intel's site and updated my wireless (Intel 6250) to 15.5.7
    Hopefully that works. Now do I just have to wait and see if it BSOD's anymore to know if it's fixed?

    hmm... please enable driver verifier and allow it to cause your system to crash then post your new files here after the crash:

    START | type verifier | make these selections - 
    1. select "Create custom settings (for code developers)"
    2. Select "Select individual settings from a full list"
    3. Check these boxes -
    ▪ Special Pool 
    ▪ Pool Tracking 
    ▪ Force IRQL checking
    ▪ Deadlock Detection
    ▪ Security Checks (Windows 7)
    ▪ Concurrentcy Stress Test (Windows 8)
    ▪ DDI compliance checking (Windows 8)
    ▪ Miscellaneous Checks
    4. Select last option - "Select driver names from a list"
    5. Click on the Provider heading - sorts list by Provider
    6. Check ALL boxes where "Microsoft" IS NOT the Provider
    7. Click on Finish 
    8. Re-boot
    Tip: if you can not boot normally after enabling driver verifier please boot into safe mode and then disable driver verifier.

    It looks like most of your mini-dumps are pointing towards: tcpip.sys however this is unlikely to be the cause of your BSOD because it's a file included in Windows Update for the Microsoft TCP/IP Driver (networking related): Driver Reference Table

    You still have some out-of-date drivers on your system that could be the underlying cause of your BSODS. Please update these drivers to Windows 8 64bit versions or remove/un-install them:

    HECIx64.sys - Intel Management Engine Interface: Driver Reference Table
    Apfiltr.sys - Alps pointing device: Driver Reference Table
    NETwNs64.sys - Intel(R) Wireless WiFi Link 5000 Series Adapter Driver for Windows 7: Driver Reference Table
    point64.sys - Microsoft IntelliPoint Filter Driver: Driver Reference Table

    To update these drivers please visit your PC manufacturers website and choose Windows 8 64bit as the OS:

    Drivers & Downloads | Dell United States

    Update Input/ALPS Electric Driver, Serial ATA/Dell-Driver, Network/Intel-Driver and anything else you think might need updating.

    Please make sure you have all the Windows Updates until you can install no more.

    I enabled the driver verifier (at least I think I did, I did it a while ago), and my computer just BSOD today. I attached my updated files.
